Definitions
- the invention relates to a device and a method for monitoring rotating components in centrifugal pumps or systems comprising centrifugal pumps.
- Centrifugal pumps are used in a variety of systems, where they are sometimes exposed to very harsh conditions. The condition of a centrifugal pump, in particular the impeller, must therefore be closely monitored depending on the application to avoid damage to the centrifugal pump or the entire system.
- DE 40 055 03 A1 shows a device for monitoring an impeller by means of a light transmitter and an optical probe. This form of monitoring requires stationary centering of the light emitter and sensor on the leading edges of the wings. However, this monitoring method is only suitable for a centrifugal pump, which promotes an optically transparent medium.
- a vacuum pump with a pump stator and a pump rotor wherein the pump rotor contains a transponder.
- sensors, a microcontroller and a memory are arranged in the rotor, which are connected to the transponder.
- a reader arranged in the stator reads the sensor data from the rotor from the transponder.
- the solution provides a device for monitoring rotating components in centrifugal pumps or systems comprising centrifugal pumps, wherein the signal transmission is acoustic, using sound waves.
- This allows a simple and secure transmission of signals from a monitored rotating component.
- liquid and solid sound-conducting media are provided on the transmission path between a first unit, the transmitting unit, and a second unit, the receiver unit.
- the advantage here is that the sound along a path is feasible and the characteristics of the way are clearly determinable.
- the phase transitions of sound between solid and liquid media may be taken into account during transmission.
- a corresponding coding of the signal takes into account losses at the phase transitions.
- the first unit has a setpoint memory, are stored in the comparison values for the measured sensor signals, in this setpoint memory thresholds can be stored, which are compared with the measured values. If a threshold is reached, a corresponding signal is sent to the receiver unit.
- Deterioration of the transmitted signal is prevented by selecting the frequency for transmitting information other than frequencies of system noise.
- System noise is understood to mean all acoustic emissions of the centrifugal pump and the components connected to it.
- the combination of different components leads to natural frequencies of the system, which depend specifically on the individual configuration of the system. This measure prevents misinterpretations in the analysis of the received signals.
- the transmission becomes insensitive to interference from the system noise mentioned above.
- an acoustic wave sensor for detecting ambient noise is provided in the second unit.
- the ambient noise can be separated from the transmitted signal, which improves the signal information.
- the first unit is integrated into a component, in particular if it is cast into the component.
- the surface of the component thus also protects the transmitting device. Due to the acoustic transmission, it is possible to integrate the first unit in a metallic component, since the acoustic signal transmission in metals works well.
- the second unit which comprises the receiver, into a metallic housing or to mount it on the outside of the housing.
- the first unit is equipped with a power supply, which in the simplest case is a battery. Generators can also be provided which gain electrical energy from the movement of the component, from vibrations or temperature gradients.
- the self-sufficient supply of energy to the first unit is particularly important if it is encapsulated encapsulated in the component. In this case, the power supply must be ensured over the lifetime of the component.
- the sensor of the first unit is designed in one embodiment of the invention for detecting component properties of the centrifugal pump or the system, for example, machine temperature, mechanical pressure or stress or component fracture.
- component properties of the centrifugal pump or the system for example, machine temperature, mechanical pressure or stress or component fracture.
- a targeted monitoring of individual components is possible.
- component fractions are by appropriate fracture sensors, as running through the component Wires are executed, easily detectable, since a break in the wire in case of component break is detected by a simple short circuit of the wire.
- operating parameters can be detected by a sensor. With the centrifugal pump these are, for example, speed, power requirement or service life. This allows further monitoring of the components whose condition can be highly dependent on these parameters.
- the senor detects properties of the pumped medium.
- the viscosity, temperature or concentration of the medium can be determined, which are then evaluated by the microprocessor. Its analysis results are transmitted to the outside world.
- a method for monitoring components with an aforementioned device in which a query of the at least one sensor takes place in cyclically recurring intervals.
- the measured sensor data are compared with setpoints from the setpoint memory and when a threshold value is exceeded, a signal is sent to the receiving unit.
- the receiving unit continuously receives noises and filters specifically for possible transmission noise, namely, the frequencies and pulse shapes that can be generated. If a signal is detected, this is evaluated and either displayed on a display and / or stealge leads to a higher-level system control.
- the invention further comprises an impeller of a centrifugal pump, which is equipped with the device for component monitoring. This simple and cost-effective device allows contactless monitoring of the impeller, wherein in the contact or wireless signal transmission neither properties of the pumped medium nor e- electromagnetic influences from the environment of the centrifugal pump must be taken into account.
- the impeller is made of a polymer material, in particular of polymer concrete or mineral casting. These materials are cast cold, so that a special protection of the cast-in first unit is not necessary.
- FIG. 1 shows a device for monitoring rotating components in circular pumps or systems comprising centrifugal pumps, consisting of a first unit 1 which is fixedly connected to the component to be monitored. connected is.
- a first unit 1 which is fixedly connected to the component to be monitored. connected is.
- the first unit directly into the component. This is useful, for example, if the component consists of a cast material which can be cast at low temperatures, for example a polymer material, in particular polymer concrete or mineral casting.
- the fully configured, self-sufficient and wirelessly designed first unit is poured, for example, in a centrifugal pump impeller.
- the component itself is not shown for the sake of simplicity.
- the first unit 1 comprises a sensor 2 for detecting component properties, which is connected to the sensor unit 3 with the first unit 1.
- sensors 2 come For example, temperature, pressure and / or material sensors or others into consideration.
- a fracture sensor is indicated, which consists of at least one wire, which veriäuft by fracture-prone areas of the component. If the component forms a crack at a point through which the wire passes, the wire will break as the crack progresses and the electrical conduction along this wire will be interrupted. In this way it is easier to detect cracks in the component. In the case of several wires connected in parallel, a progression of cracking can also be observed.
- a microprocessor 4 for analyzing sensor signals directly evaluates the data recorded by the sensor 2 and forwards the analysis result to a transmitting unit 5 for transmission to a receiver spatially separated from the monitored component.
- the frequency of the sensor query depends on the probability of an expected event. It significantly influences the energy requirement. A low check frequency will result in long battery life and will be further improved if the system is put into sleep mode or paused during the pauses between two polls.
- the component monitoring by the acoustic data transmission according to the invention represents the safest and most cost-effective variant within the structure used.
- the signal 8 can be embodied as an acoustic message telegram which can contain different frequencies, pulse sequences or combinations thereof. By repeating the same signal, transmission errors can be avoided.
- the design of the sound generator, which forms the transmitting unit 5 in this embodiment depends strongly on the information to be transmitted, the frequencies used and the surrounding conveying medium, since this must be run through by the signal 8. It should be noted that the signal in an embedded first unit must first leave the component, with a transition between the solid component and the liquid or solids-laden medium takes place.
- FIG. 1 further shows a second unit 9, which is equipped with a receiver unit 10. This is installed in use with a centrifugal pump in or on the pump housing. Depending on the load of the pumped medium, the receiver unit must be provided with protection. As with the first unit 1, it may be advisable to pour the second unit 9 directly into the pump housing.
- the receiver 10 is tuned to the transmitter 5 with respect to its detectable frequency range.
- the detected signals are fed to an evaluation unit 11.
- the evaluation result can be displayed in the embodiment shown directly on the pump, for which a corresponding display means 12 is provided.
- the display can be acoustic or optical. Alternatively, it is possible to forward the evaluation result to a higher-level system control, for which purpose the connection 13 is provided.
